Wireless – Security

The next screen is the Wireless – Security screen which allows you to select the network authentication method and to enable or disable WEP encryption. Note that depending on the network authentication that is selected, the screen will change accordingly so additional fields can be configured for the specific authentication method.

Network authentication methods include the following—

• Open—anyone can access the network. The default is a disabled WEP encryption setting.

• Shared—WEP encryption is enabled and encryption key strength of 64-bit or 128-bit needs to be selected. Click on Set Encryption Keys to manually set the network encryption keys. Up to 4 different keys can be set and you can come back to select which one to use at anytime.

• 802.1X—requires mutual authentication between a client station and the router by including a RADIUS-based authentication server. Information about the RADIUS server such as its IP address, port and key must be entered. WEP encryption is also enabled and the encryption strength must also be selected.

• WPA—(Wi-Fi Protected Access)— usually used for the larger Enterprise environment, it uses a RADIUS server and TKIP (Temporal Key Integrity Protocol) encryption (instead of WEP encryption which is disabled). TKIP uses128-bit dynamic session keys (per user, per session, and per packet keys).

• WPA-PSK (Wi-Fi Protected Access – Pre-Shared Key)—WPA for home and SOHO environments also using the same strong TKIP encryption, per-packet key construction, and key management that WPA provides in the enterprise environment. The main difference is that the password is entered manually. A group re-key interval time is also required.

• WPA2 (Wi-Fi Protected Access 2)—second generation of WPA which uses AES (Advanced Encryption Standard) instead of TKIP as its encryption method. Network re-auth interval is the time in which another key needs to be dynamically issued.

• WPA2-PSK(Wi-Fi Protected Access 2 – Pre-Shared Key)—suitable for home and SOHO environments, it also uses AES encryption and requires you to enter a password and an re-key interval time.

• Mixed WPA2 / WPA—during transitional times for upgrades in the enterprise environment, this mixed authentication method allows “upgraded” and users not yet “upgraded” to access the network via the router. RADIUS server information must be entered for WPA and a as well as a group re-key interval time. Both TKIP and AES are used.

(19)

WAN

Configure the WAN settings as provided by your ISP.

(20)

Find out the following values from your ISP before you change them.

• VPI: Virtual Path Identifier. The valid range is 0 to 255. • VCI: Virtual Channel Identifier. The valid range is 32 to 65535. • Service Category: Five classes of traffic are listed—

o UBR Without PCR (Unspecified Bit Rate without Peak Cell Rate)— UBR service is suitable for applications that can tolerate variable delays and some cell losses. Applications suitable for UBR service include text/data/image transfer, messaging, distribution, and retrieval and also for remote terminal applications such as telecommuting.

o UBR With PCR(Unspecified Bit Rate with Peak Cell Rate)--

o CBR(Constant Bit Rate)—used by applications that require a fixed data rate that is continuously available during the connection time. It is commonly used for uncompressed audio and video information such as videoconferencing, interactive audio (telephony), audio / video distribution (e.g. television, distance learning, and pay-per-view), and audio / video retrieval (e.g. video-on-demand and audio library).

o Non Realtime VBR(Non-Real-time Variable Bit Rate)—can be used for data transfers that have critical response-time requirements such as airline reservations, banking transactions, and process monitoring.

o Realtime VBR(Real-time Variable Bit Rate)—used by time-sensitive applications such as real-time video. Rt-VBR service allows the network more flexibility than CBR.

(21)

The following screen shows the below types of network protocols and encapsulation modes—

• PPP over ATM (PPPoA) • PPP over Ethernet (PPPoE) • MAC Encapsulation Routing (MER) • IP over ATM (IpoA)

• Bridging

(22)

The following screen allows you to enter PPP username and password as well as make any selections regarding your connection.

• Dial on demand: Allows you to manually connect to the Internet so you are not permanently connected. Idle timeout timer is included.

Settings can be configured for the following—

• AP Isolation—if you select enable, then each of your wireless clients will not be able to communicate with each other.

• Band—a default setting at 2.4GHz – 802.11g

• Channel—802.11b and 802.11g use channels to limit interference from other devices. If you are experiencing interference with another 2.4Ghz device such as a baby monitor, security alarm, or cordless phone, then change the channel on your router.

• 54gTM _Rate_—_{the wireless link rate at which information will be received and} transmitted on your wireless network.

• Multicast Rate—the rate at which a message is sent to a specified group of recipients.

• Basic Rate—the set of data transfer rates that all the stations will be capable of using to receive frames from a wireless medium.

• Fragmentation Threshold—used to fragment packets which help improve performance in the presence of radio frequency (RF) interference.

• RTS Threshold (Request to Send Threshold)—determines the packet size of a transmission through the use of the router to help control traffic flow.

• DTIM Interval—sets the Wake-up interval for clients in power-saving mode.

• Beacon Interval—a packet of information that is sent from a connected device to all other devices where it announces its availability and readiness. A beacon interval is a period of time (sent with the beacon) before sending the beacon again. The beacon interval may be adjusted in milliseconds (ms).

• Xpress Technology—a technology that utilizes standards based on framebursting to achieve higher throughput. With Xpress Technology enabled, aggregate throughput (the sum of the individual throughput speeds of each client on the network) can improve by up to 25% in 802.11g only networks and up to 75% in mixed networks comprised of 802.11g and 802.11b device.

• 54g Mode—54g is a Broadcom Wi-Fi technology.

• 54g Protection—the 802.11g standards provide a protection method so 802.11g and 802.11b devices can co-exist in the same network without “speaking” at the same time. Do not disable 54g Protection if there is a possibility that a 802.11b device may need to use your wireless network. In Auto Mode, the wireless device will use RTS/CTS (Request to Send / Clear to Send) to improve 802.11g performance in mixed 802.11g/802.11b networks. Turn protection off to maximize 802.11g throughput under most conditions.
